I feel like I've been mindfucked like the fist of an angry god.

Cockroach-tan is falcon punch'd -she does love it- and Hirose nearly finish her (mindfuck 1). Then, a bit after Hirose finally becomes blind again (mindfuck 2), Cockroach-tan begins to leave the village for good. Meanwhile Hirose goes nuts. At the end, two nice guys (and that freaking old man) are getting ready to shot Cockroach-tan down and Hirose suddenly save her, while being still blind (mindfuck 3). Preview indicates next episode will be the last.
